Hi
The file permissions that ls -l shows up does not have executable permissions for the user i.e you i.e davidlee. So you need to set the executable permissions for the script file (myscript). to do this give chmod u+x myscript
the ls -l myscript will then show
-rwx-r--r-x
i.e you now have the executable rights and now you can run myscript by typing just the filename.
Hope this works.

YAPP(1) User Contributed Perl Documentation YAPP(1)
NAME
yapp - A perl frontend to the Parse::Yapp module
SYNOPSYS
yapp [options] grammar[.yp]
yapp -V
yapp -h
DESCRIPTION
yapp is a frontend to the Parse::Yapp module, which lets you compile Parse::Yapp grammar input files into Perl LALR(1) OO parser modules.
OPTIONS
Options, as of today, are all optionals :-)
-v Creates a file grammar.output describing your parser. It will show you a summary of conflicts, rules, the DFA (Deterministic Finite Au-
tomaton) states and overall usage of the parser.
-s Create a standalone module in which the driver is included. Note that if you have more than one parser module called from a program,
to have it standalone, you need this option only for one of your parser module.
-n Disable source file line numbering embedded in your parser module. I don't know why one should need it, but it's there.
-m module
Gives your parser module the package name (or name space or module name or class name or whatever-you-call-it) of module. It defaults
to grammar
-o outfile
The compiled output file will be named outfile for your parser module. It defaults to grammar.pm or, if you specified the option -m
A::Module::Name (see below), to Name.pm.
-t filename
The -t filename option allows you to specify a file which should be used as template for generating the parser output. The default is
to use the internal template defined in Parse::Yapp::Output.pm. For how to write your own template and which substitutions are avail-
able, have a look to the module Parse::Yapp::Output.pm : it should be obvious.
-b shebang
If you work on systems that understand so called shebangs, and your generated parser is directly an executable script, you can specifie
one with the -b option, ie:
yapp -b '/usr/local/bin/perl -w' -o myscript.pl myscript.yp
This will output a file called myscript.pl whose very first line is:
#!/usr/local/bin/perl -w
The argument is mandatory, but if you specify an empty string, the value of $Config{perlpath} will be used instead.
grammar
The input grammar file. If no suffix is given, and the file does not exists, an attempt to open the file with a suffix of .yp is tried
before exiting.
-V Display current version of Parse::Yapp and gracefully exits.
-h Display the usage screen.
BUGS
None known now :-)
